I saw that one this morning, I've watched it at least four times since, and I'm going to watch it a lot more in the future. So much WIN. I need that movie. Now. XD
After seeing this trailer I'm so incredibly psyched for this film. Then again, many trailers have looked absolutely wonderful only for the movie to suck in the end. I'm glad they are making The Hobbit a much lighter film than LOTR. It matches the book well.
